MOJAVE, Calif., Aug. 31, 2005/Satnews Daily/ — XCOR Aerospace, Inc. announced on Monday it has successfully completed its first series of tests on a 50 pound thrust rocket engine fueled by methane and liquid oxygen.
XCOR chief engineer Dan DeLong said the engine tests gave XCOR operational familiarity working with methane. “We have extensive experience with liquid oxygen, so running an engine with a cryogenic fuel wasn't a stretch for us,” he said.
Future generations of the 3M9 engine are intended for use as Reaction Control Systems (RCS) and satellite maneuvering systems. The advantages of a methane-fueled engine include long-term on-orbit storage, higher density than hydrogen engines, higher performance than kerosene engines, and the potential for using methane derived from the Martian atmosphere as a fuel source.
The engine tests took place at XCOR's facilities at Mojave Spaceport and consisted of 22 engine firings totaling 65 seconds. The longest engine firing was 7 seconds. This first series of tests was done with self-pressurizing propellants. Pressure-fed and pump-fed versions are also in development.
